Yes I did and I only ever had automated reply that someone would be in touch within 48 hours then another 3 days later asking me to let them know how good there customer service was, I never received a reply to that either lol. Whilst I never expected amazon speed delivery I would expect it within a couple of months especially when they still show the items as being in stock.
Except the 350z/370z and Infiniti's (Nissan equivalent of a Toyota Lexus) are still proper Japanese cars not the Renault (poo)
I'd go Denso first, Ngk 2nd,both great but go for iridiums
Even I use iridium plugs in my old cars,wouldn't be bothered with standard plugs anymore...Fit iridiums and forget about them lol.
